Raising Atlantis?Review: The Two Trotskyisms Confront Stalinism. Edited Sean Matgamna. Workers’ Liberty. 2015.
The second volume of The Fate of the Russian Revolution is, like the first, aimed at establishing, the present day importance of one of those distant figures, Leon Trotsky In hisIntroduction to The Two Trotskyisms Sean Matgamna draws how own parallel with the heresiarch Arias and his followers. The reference is not, as one might expect, to the unequal contest between the founder of the Fourth International’s circle of supporters and Stalin’s Established Marxism-Leninist Church. It is to disputeswithin the Trotskyist movement, “The Heterodox were the Arians, and the Orthodox the Catholics of post-Trotsky Trotskyism.” The leader of the – ‘heterodox’ Trotskyist – Alliance for Workers’ Liberty (AWL) argues that this division, which originated in the 1940s, amongst those who “embodied the great truths of Marxism” the only “authentic Marxist-communist tradition” was of lasting significance. Revolutionary socialists, “must go back to re-examine the old debates and the flaws and lacunae in the political legacy which Trotsky left at his death – back to 1940.”
